Only a few reasons.. if engine not turning over at all its seized motor, it could be a bent valve and stopping the piston from completing its full stroke. or a piston rod. If engine turns over and not starting it could be fuel, electrical, or carbies jets, or valve timing. Hope this helps Ken

Tire pressure is printed on the sidewall of the tire itself.. probably 40 to 44psi or so. Should be labeled on the tire itself beside the letters (psi)

Sounds like you need to take it to a shop that kinda knows what they are doing. If they have problems they can call cobra themselves. As a shop the aftermarket companies are usually pretty good about helping out since most of their product is sold or installed in aftermarket shops. With that being said. I would start by dropping the clips up one notch and see how that works. By sliding it up one notch it should run a little leaner . If it's better but doesn't cure the problem then go up one more. If it does clear up the black smoke then there you go. Generally cobra will tell you in the directions what common jets to install. They even have a section for higher elevations as well. If not in the directions they usually do on their website. Hope this helps a little. I’m happy to assist further over the phone at https://www.6ya.com/expert/robert_5bac37c3cb991fdb

First remove cables and note where from. Throttle cable, throtle return cable and choke cable. Then loosen clips securing hoses to engine block , pull away hoses from air box then gently but firmly wiggle carbs out.

You need a new set of cam plugs. they fill the half moon holes necessary for the cam bearing journals to be align bored. You will also need a valve cover gasket. it would be a good time to checkhe valve clearance, but if you don't have tools or shims you would be lost.Sealer is also in order around the edges where there are sharp corners to assure a god seal between the rubber plugs and the new gasket.

This sound like a fuel supply problem, perhaps the fuel tap is stuck. you could try it with the tap in the pri (prime) position, if this helps it may need a new fuel tap rebuild kit

disconnect a positive wire going to one of the coils and put a paper clip in it,put it on metal and crank the bike to see if it sparks, we can then go on from there.

thanks

Yes, this could be the problem. With you turning the bike over on the starter a lot of demand is placed on the battery and it may simply be not supplying enough to the coils. Does it turn over slowly? First try fully charging the battery, and see if this solves the problem.

17 is correct Frank mesured from the base of the carburetor. Meaning the flat surface that the bowl bolts to, from the part of the float furthest away. With the needle just touching the seat.
If you have set this correctly and are not getting fuel the next thing to check is that the needle and seat are not binding with a bit of grit (rarely happens) or that there is a problem with the petcock or filter. If it is vacume operated try sucking the vacume tume and see if fuel runs out of the hose into a container at a decent flow rate. If not vacume operated check the flow into a container when the tap is turned on. lastly check the fuel line does not have a kink or collapse caused by inferior line type or sharp bend.
Hope you get it going soon mate.

First thing I would do is change spark plugs, then put plug back in plug wire, rest against head metal. crank your bike , watching for good blue spark jumping from end of plug to head metal .
If spark is blue, your good, put your battery on a slow charge 2amp and let charge for 2 hours
or more . Empty fuel tank by draining , replace fuel filters, and use new gas when refil. It may
be hard to start at first but let it warm up . If you need to 1/2 choke it ? Do it for a while . It will
come out of this bad spell after the new gas has taken over. You should be good to go. Ok
